The side and end walls and t-op are spacing sleeve or collar i8 (see particularly 11o Fig. l0). Loosely encircling sleeve 48 so as to be longitudinally movable thereon is a driving clutch 49. Clutch 49 is provided with a pair of pins 50 rigidly secured there to. Pins 50 project into holes 5l in crank 40 when clutch 49 is in non-driving position, as shown in F ig. l0. and through holes 5l into corresponding holes 52 in crank disc 25 when clutch 49 is in driving position, as shown in Fig. 9. Pins 50 always project into crank 40, so that clutch 49 and the pins are oscillated whenever the motor is in operation. l/Vhen the clutch is in driving posi- 'tion the pins also project into the openings in crank disc 25 and the tub is accordingly oscillated with crank 40 and clutch 49.

The clutch is thrown into and out of driving position by a handle on the outside of the housing. Clutch 49 is provided through a portion of its circumference with a groove 55. Into grooves 55 projects a pin 56 which extends eccentrically from a collar 57. Collar 57 is rigidly secured to a shaft 58 journaled in bearings 59 and 60 secured to end wall 8. Shaft 58 has a beveled pinion 6l keyed or otherwise rigidly secured thereto. Pinion. 6l meshes with a bevel pinion 62 carried by a shaft also journaled in bearings 60. This shaft is provided with or bent into the form of a handle 63, which is operable from the outside of the housing. vVV'hen shaft 58 is turned by handle 63 the eccentric projection 56 slides clutch 49 along sleeve 48 into locking or non-locking position. lThe pin and slot connection between projection 56 and clutch 49 allows the clutch to be freely oscillated at all times and to be thrown into and out of driving position while the motor is in operation. By providing a movable clutch member, crank 40 may be made axially immovable so that connecting rod 41 is retained substantially in the same plane. This reduces the liability of bending 'the connecting rod and allows the use of connections having tighter lits .and consequently less lost motion and other disadvantages.`

To insurey that the opening in the top of the tub is in proper position when the oscillation is stopped and to lock the tub in this position, a latch is operated simultaneously with the operation of the driving clutch. Rigidly secured to shaft 58 is a collar 65. Collar 65 has a spirally Urooved cam 66 secured to its periphery. lanto the groove of this cam projects a roller head 67 of a bolt 68. Bolt 68 is slidably carried by bearing 59 and 'when advanced may project into one or the other of two holes 69 and located in the circumference of crank disc 25.

l/Vhen force is exerted on handle 63 to move the same to cause the disengagement of the driving clutch, the spiraled groove of cam 66 tends to force bolt 68 outwardly.

Bolt 68 engaging the surface of crank disc 25, prevents the clutch from being thrown until one or the other of holes 69 and 70 comes opposite the bolt. The pressure on the handle then throws the clutch to nondriving position and advances bolt 68 to locking position. The oscillation of the tub is thus stopped and the tub is locked with its opening either at the top or slightly tilted toward the front, as deslred.

"When handle 63 is moved to throw the clutch to driving position, bolt 68 is simultaneously withdrawn. VThe bolt releases the tub just before the clutch reaches driving position and then the tub is oscillated by the motor.

Having described my invention, what I claim is l. A washing machine having a pivotally mounted tub, a crank disc resiliently connected to saidtub to move the same, operating mechanism for oscillating said crank disc, a clutch for connecting and disconnecting said crank disc and mechanism, and a stop acting simultaneously with said clutch and positively arresting the oscillation of the crank disc, whereby the tub is brought to rest in one of several definite positions.

2. A washing machine having a pivotally mounted tub, a crank disc resiliently connected thereto, driving mechanism, a yclutch associated with said driving mechanism, a manually operated element adapted to throw said clutch into and out of engagement with 3. A washing machine having a pivotally `mounted tub, a crank disc connected thereto,

driving mechanism, a clutch associated with said driving mechanism, a manually operated element adapted to throw said clutch into and out of engagement with said crank disc, means adapted to lock the tub in a delinite position, and means controlled by said element and adapted to operate ysaid first mentioned means. l

j 4. A washing machine having a pivotally mounted tub, a crank disc connected thereto, driving mechanism, a clutch associated with said driving mechanism, a manually operated element adapted to throw said clutch into and out of engagement with said crank disc, said crank disc having a plurality of recesses, a locking member adapted to enter any one of said recesses, and means controlled by said element and adaptedto operate said locking member, whereby said tub may be locked in any one of several definite positions.

5. A washing machine, having a pivotally mounted tub, a crank disc connected thereto, driving mechanism, a clutch associated with said driving mechanism, a manually oper ated element adapted to throw said clutch into and out of engagement with said crank disc, said crank disc having a plurality ont recesses, a locking member adapted to enter any one of said recesses, and a spirally grooved collar associated with said element whereby said locking member may be positioned in any one of said recesses and the tub locked in any one of several deinite positions.

6. A washing machine having a pivotally mounted tub, a crank disc resiliently connected thereto, power transmitting mechanism including a crank for oscillating said crank disc, a clutch axially movable on the. axis of said tub and for operatively connecting and disconnecting said crank and crank disc, and means including a handle for operating said clutch.

7. A washing machine having a pivotally mounted tub, a crank disc resiliently connected to the tub, power transmitting mechanism for oscillating said crank disc, a clutch for connecting and disconnecting said crank disc and mechanism, a stop adapted to look the crank disc in any one of several definite positions, and manually operated means adapted by a single operation to move the stop out of engagement with the crank disc and to move the clutch into operative engagement with the crank disc and by a reverse operation of the manually operated means to move the clutch out or' engagement with the vcrank disc and to move the lock into engagement with said crank disc.

8. A washing machine having a pivotally mounted tub, a crank disc connected to the tub, a power transmitting mechanism for oscillating said crank disc, a clutch axially movable on the axis of said tub 'for connecting and disconnecting said crank disc and mechanism, a stop or locking the disc in any one oi' several definite positions, and manually operated means adapted by a single operation to simultaneously move the clutch ont of engagement with the disc and the stop into engagement with the disc, said clutch being entirely disengaged from said disc before the stop is brought into engagement with said disc.
